Also, determine the net quantities needed if there are 30 of the base and 75 of the clamp in stock.

As the production planner for Xiangling Hu Products, Inc., you have been given a bill of material for a bracket that is made up of a base, 1 spring, and 4 clamps. The base is assembled from 1 clamp and 2 housings. Each clamp has 1 handle and 2 castings. Each housing has 1 bearing and 1 shaft. There is no inventory on hand. a) Design a product structure noting the quantities for each item and show the low-level coding. Match each number in the structure below with the corresponding item. \begin{tabular}{c|l} Number & \multicolumn{1}{|c}{ Item } \\ \hline I & Spring (1) \\ II & Housing (2) \\ III & Casting (2) \\ IV & Shaft (1) \end{tabular} Bracket b) Determine the gross quantities needed of each item if you are to assemble 75 brackets.
